Solve the following system of equations by substitution and select the correct answer below:

2x − 4y = 24
4x − 12y = 36

x = 18, y = 3

x = 18, y = −3

x = −18, y = 3

x = −18, y = −3

x = 18, y = 3

Step-by-step explanation:

Given system of liner equation is :-

From (1), we get

.........(3)

Substitute the value of x in equation (2), we get

Now, substitute the value of y in (3), we get

x = 18, y = 3

do have an equation or graph or

step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :
